BRICK-SCORING MECHANISM.

To all whom it may concern Be it known that 1, WILLIAM F. Rrorrnr, a citizen of the United States of America, residing at Ashtab'ula, in' the county of Ashtabula and State of Ohio, have invented new and useful Improvements in Brick-Scoring Mechanism, of which the following is a specification.

The object of the invention is to provide simple and efficient means for scoring or scratching bricks and similar buildingblocks to produce the efi'ect in the completed brick of a rubble or cut stone face and for forming a plaster key; and with these objects in view, the invention consists in a construction and combination of parts, ofwhich a preferred embodiment is shown in the accompanying drawings, wherein Figure 1, is a view of an apparatus embodying the rotary comb adopted for the apparatus indicated.

Figure 2, is a detail elevation of one of the comb supporting standards.

Figure 3, is a transverse sectional View in detail of the rotary comb.

Figure 4, is an elevation of the apparatus arranged to operate upon opposite edges of a brick or building block.

Figure 5, is an end view of the form shown in Figure 4 to show the means of adjustment of the comb operating bracket.

Figure 6, is a detail section on the plane indicated by the line 6-6 of Figure 4-.

Figure 7, is a modified form of the device wherein stationary combs are employed for simultaneous operation upon the side and end edges of a brick or block.

The invention consists essentially in a comb such as that indicated at 10 in Fig ure 1, which in this instance consists of a frame or roll 11 provided with rotary pins or teeth 12 and disposed in operative relation with the rest or support 13 upon which the brick or block is to be scored is arranged and carried progressively within the range of operation of the comb so as to enable the teeth of the latter to score the exposed surfaces of the brick or block, the latter being subjected to the operation while in a plastic form as when just delivered from the press or moulding apparatus, to the end that when the brick is baked or burned, the treated surfaces thereof will pre sent the appearance of tooled stone and a Specification ofLetters Patent.

mortar applied thereto. In the construction illustrated, as above indicated, the drum i is carried by a shaft 14: mounted in bearings in suitable standards 15, the bearing blocks 16 being engaged by the adjusting screws 17 by means of which the position of the drum with relation to the support 13 may be adjusted to suit the thickness ofthe brick or block to be treated or the depthto which it is desired that the teeth or pins of the comb shall penetrate or score the surfaces of the same. The shaft may be driven by any suitable means such as a counter shaft 18 having a universal connection 19 with the driving shaft 20 which may be connected, if preferred with the direct motion or any other means of operation. The body of the drum or roll may be of wood or like material of which. the inner ends of the teeth or pins are embedded as indicated in Figure 3.

The modified construction shown in Figure 4 consists of a plurality of combs 1O disposed in opposite relation at opposite edges of a support or rest 13 for the bricks or blocks and are thus adapted to operate upon opposite edges of a brick or block arranged upon the said support. the spindles 21 of said combs being carried by brackets 22 which are adjustably fitted in slots 23 in the standards or uprights 24 and are held in place bv nuts 25 to the end that the combs may be adjusted toward and from the plane of the support or rest 13 and may also be adjusted toward and from each other to suit the dimensions of the bricks or blocks to be scored. The spindles of said combs may be fitted as shown in Figure 4 with bevelled gears 26 with which mesh stem gears 27 adjustably secured to a drive shaft 28 receiving motion for example through a drive chain 29. The shaft 28 in the construction illustrated is supported by brackets 30 which are also adapted for adjustment to suit the adjustment of the combs as by the construction shown in Figure 6. In the further modified construction indicated in Figure 7 the combs 10 are of stationary form having supporting bars 31 in which are secured the teeth or pins 32 and adapted to be arranged as shown so as to hold them for example, upon one side of the brick and two opposite edge surfaces of a brick or block and move progressively in relation there with.

The invention having been described, what is claimed as new and useful is A mechanism for scoring the faces of bricks or blocks prior to the baking thereof comprising a fixed rest, standards disposed respectively on opposite sides of the rest and interconnected at their upper ends to provide a frame. rotary combs disposed on opposite sides of the rest and between itand the standards. the combs being provided with shafts. brackets in which the shafts of the combs are rotatably mounted, the

in which said transverse shaft is journalled.

In testimony whereof he affixes his signature.
